Damage modifier effect Options

[egm]

Hello,

I can't get my spell to work properly: all that i want is to set the damage inflict by the caster to 0 (no damage at all).
I have also a "Set melee effect" working in this spell. can someone give me a tip?

I've tried #73 and #285 effects (separatly and at the same time): using a flat value of 0. But in-game, my warrior always inflicts damages.

Effect 250is a little odd for me: I made searches, and the damage modifier is always set to 20 (to inflict maximum amount of damages according to the various spells descriptions)- I guess it's not really useful for my purpose

If you have a tip to make my character inflict 0 damage at each strike, juste tell me!
